Position

Hi Grovkillen,

"Returns the starting position of a substring in a string. The search commences at the position specified in start. If found the starting position of the substring is returned in the result variable. If no match is found this value will be zero."
Yes, we have a Custom Scripting Service. Message me or go here

Yes that is understood but if you look at my example you'll see that the string containing "1" (or "12" or "123" for that matter) will also return zero.

If it's by design then the start position of zero shouldn't be allowed.
